Intelligence Briefing: 141.101.74.143
The IP address 141.101.74.143 was associated with Cloudflare (ASN 13335) and classified within the CLOUDFLARE-EU network block. Ownership records linked the address to the organization, categorizing the infrastructure as a Content Delivery Network (CDN) with a "Firewalled / No Services" designation. The IP presented a low-risk reputation profile with a risk score of 25 and zero blacklist entries.
Operational analysis indicated no open ports or active service banners. Threat intelligence feeds did not flag the address as a known attacker, spam source, or Tor exit node. Behavioral metrics showed no honeypot hits, enumeration strikes, or WAF violations.
However, data analysis identified a significant contradiction between geolocation claims and physical network constraints. While the IP was geolocated to Dallas, TX, RTT measurements of 70ms contradicted the minimum possible latency of 160ms for that distance. Despite this anomaly, the IP showed no persistent malicious activity between August 29 and September 18, 2026. Security teams were advised to monitor the address due to data signal contradictions.
